Penn’s athletic director Grace Calhoun left on April 19 to become AD at Brown, her alma mater.

And the bigs in College Hall — president Amy Gutmann and her board of factotums and supernumeraries — have yet to announce a replacement.

Which tells you how unimportant athletics have become at what was once a national power (in the 1940s and 1950s) and lately a respected school that always was in the mix for March Madness.

Alas, no more.

In the meantime, right up the road Mollie Marcoux Samaan. the athletic director at Princeton the last seven years, yesterday was named as the ninth commissioner of the LPGA Tour, and the second woman to hold the position since the LPGA was founded 71 years ago.

She replaces Mike Whan, who got the LPGA back on track during his 10 years and left early this year to become CEO of the U.S. Golf Association.
